How single file or LUN restore works

If a file or LUN is accidentally deleted, modified, or corrupted, you can restore such a file or LUN from a Snapshot copy to a specific point in time. You can copy the file or LUN to a new location.

In a single file or LUN restore operation, a set of files or LUNs or a single file or LUN from a single Snapshot copy is copied from one volume to another volume. The volume from which the file or LUN is restored need not be a SnapVault secondary volume, and the volume to which the file or LUN is restored is not restricted to the volume from which the files or LUNs were initially backed up. You can restore the file or LUN from a volume that is not a SnapVault secondary volume, and you can restore to a volume that is not the volume from which the files or LUNs were originally backed up.

In single file or LUN restore operation, the volumes need not have a common Snapshot copy. If a common Snapshot copy exists, an incremental restore is performed for those files or LUNs that exist in the common Snapshot copy.

Note: You cannot change the compression capability when the single file restore operation is in progress.
